IPA: /mjuˈteɪʃənəli/
KK: /mjuˈteɪʃənəli/
In a way that relates to changes in genetic material or characteristics.
The virus evolved mutationally, adapting to its environment over time.
Mutationally → It is formed from "mutate" (from Latin "mutare", meaning to change) and the suffix "-ion" (indicating the action or process) combined with "-ally" (meaning in a manner). The word "mutationally" refers to the manner in which changes occur, particularly in a biological or genetic context.
Think of 'mutate' meaning to 'change' — so 'mutationally' describes how something changes.
